Introduction

RibbonsTop-Entry products include a connector, hood, and associated hardware. They are typically used at the end of a cable, where it is subject to physical strain and protection of the termination area is required.

  • Includes all hardware required to attach hood to connector.
  • Bail latching sockets have latch hardware integral to connector body, making cable assembly less costly.
  • Bail latching plugs include notches that lock with industry-standard bail-lock sockets.

Features

Terminates Discrete Wire (loose or jacketed cable) with ultra-low-resistance solder connections.

  • Metal shell provides grounding and shielding capability.
  • Available in plug and socket styles in 50 position.
  • Designed for panel mount, 180° (Top-Entry), or 90° (Standard) / 270° (Reverse) End-Entry cable applications.
  • All plugs lock with InstaLatch passive latch feature for automatic latching.
  • Industry-standard bail latch feature available for locking/unlocking without tools in applications such as SCSI-1 and Centronics.
